This blog post is an interview with Kristian Parton, from the University of Exeter who is studying the effects of plastic pollution on sharks. He’s @KjParton on Twitter
What are some of the threats to sharks today?
KP- Blimey, where do I begin. It’s probably safe to say sharks (and rays) are some of the most threatened species in the worlds’ oceans. They have a variety of different threats, the most notable of which are without doubt overfishing and bycatch – these two practices are responsible for the removal of the greatest number of sharks from the seas. Then we move onto problems such as shark finning for traditional medicines, climate change, ocean acidification and plastic pollution!
Why should we save sharks?
KP- Well, not only are they absolutely awesome, they’re actually really important for the health and well-being of marine ecosystems. Sharks are top predators in the marine food web and consequently if you remove them this can have knock on impacts all the way down. I think it’s also vitally important to save threatened species for future generations. I remember the first time I saw a shark in the wild, it’s an experience I’ll never forget and I want the people who come after us to be able to experience that too.
How did you get started researching the impact of plastic pollution on sharks?
KP-Initially I was an undergraduate at the University of Exeter in the UK studying zoology, but took all the marine modules I possibly could. I knew I wanted to move straight into research after I graduated and have loved sharks since I was a young boy – so it was a no-brainer for me. It’s difficult to avoid the topic of plastic pollution at the moment, particularly in regards to turtles, seals and dolphins, but I read into a little bit more about how it might be impacting sharks and rays. It turns out the scientific literature is fairly scarce on the issue, so I dived in head first looking to expand our knowledge on how sharks and rays are really impacted by plastics – most notably via entanglement and ingestion.
Why did you found the Shark and Ray Entanglement Network?
KP-We founded ShaREN after our first publication a few weeks ago because we realised the issue of shark and ray entanglement in marine debris was severely underreported. In our research paper, we used Twitter reports to help document entanglement cases for sharks and rays and realised that it was occurring at higher levels on Twitter than it was in the scientific literature. We realised that the best way to try and collect more data on the topic was to create a citizen science platform where people around the world could submit their sightings of entangled sharks and rays. ShaREN is growing quickly and we’ve already had over 30 reports of entanglement since its creation a few weeks ago, but are always on the look out for more reports! If you do spot any entanglement incidents for sharks and rays, you can find the report form here: Shark and Ray Entanglement Network
Who’s your favorite Star Wars character(s)? (Both the interviewer and interviewee are big Star Wars Fans! Are you too? My favorites are the droids, R2D2 and BB-8)
KP-Hahah – that’s a tough question! I grew up around the prequels so I have a soft spot for them. I’d probably initially say Anakin, but he ends up going a bit mad (obviously) so I’d lean towards Ewan McGregor as Obi-Wan – what a legend! I can’t wait for the new TV series based around him.
